*  Fixed obdecho persistent object size at 1 MByte.

*  Changed test_brw data verification tests to work on a fixed 4k block
   rather than on page size to allow different page sized servers and
   clients.

land b_size on HEAD for 1.2

Adds support for client-side write cache accounting via OST write credits
(grants).  There is not yet a "correction" algorithm for grants if they
get out of sync between the client and OST (OST can handle clients who think
they have grant but do not).  Peter had previously suggested that grants
should decay over time (faster on the clients than on the OSTs) so idle
nodes do not consume space they aren't using.

Use /proc/fs/lustre/osc/OSC*/cur_grant_bytes (and existing cur_dirty_bytes)
to check client-side cache values.

Includes lustre-side changes for lfsck support (create files with
specific objids, create specific objids on OSTs).

Also includes some changes to the testing scripts (local.sh, lov.sh, acc-sm)
so that they include a "client nid '*'" client and can be used for sanityN.sh
testing.  This has been put into the main acceptance-small.sh loop so that
sanityN.sh will be run on both single and multi-OST setups.

replace OBD_IOC_LIST ioctl with reading /proc/fs/lustre/devices

The principal change here is ptlrpc_connect_import and recovery are
merged and are now asynchronous and are run on ptlrpcd.

This branch also includes fixes for

  2477 (this was the initial bug)

  2355 recover for initial connections

  1934 (b_1934 was merged directly to b_recovery)

  1901 block all file creations until orphan recovery completes

  2423 client remove rq_connection from request struct

  2640 conf-sanity test_5, and proper cleanup in umount when
       cleanup log is not availale.

  2670 recovery timer race

  2532 mdc_close recovey bug

And few others that werent' filed.

fix bug in sanity test 60 where llog_test was oopsing in insmod on ia64

Approved by Andreas Dilger.

r=shaver

Delete IOC_CONNECT,DISCONNECT and use obd_self_export instead
of creating connections for lctl. Also delete the IOC_DEVICE comamnd
and make the ioctl interface stateless.  The lctl probe command is now
a noop, and lctl device is still used to set the device, although the
current device state is only saved in lctl now, and not the kernel.

- export brw histograms from the filter that record discontiguous offsets
  in the brw request and discontigous blocks that satisfy the request
  (seen as /proc/fs/lustre/obdfilter/$name/brw_stats)

Fix for bug 974, Also adds a test to check for OOM (modified script from
bug 1135), fixes to sanity.sh's test 45 to obtain a grant (closes 2387).

fix for #2319, make osic to be allocated separately and implement proper
refcounting for it.
Also adds a test to sanity.sh that checks for (fixed) crash.

lfs catinfo <keyword>
Fetching logs information from client node. Now keywords include:
config and deletions. Others will be added in future.

r: Andreas

Make log record alignment 8 bytes.

We don't need to re-check the atime/mtime set flags in fsfilt_ext3_setattr,
we do it already in mds_fix_attr().

Also fix /proc variables to be int, as that is what the functions expect.

*   socknal Makefile.am fix

bumped the kernel patch version to 23, but really only vanilla-2.4.20 changed

Final version of the read performance patch, tested on ALC.

r=shaver
Fix the 3x read performance regression caused by clobbering the
client's i_blksize number, which sets an upper bound on the amount of
readahead done by a single ll_readpage.  The practical upshot was that
all reads after the first one would do 4k to the disk and 4k over the
wire.
